Master Engine References
Every factory parts diagram, wiring loom, engine-attached electrical component and torque figure for one engine — followed across every car it was fitted to. Built for the engine builder and the transplant.
Weighing up a 16V into your Mk1 or Mk2? This is the only reference built for that job. Every factory parts diagram for the KR, PL, 9A and ABF, the wiring looms and engine-attached electrics that have to come across with the engine, and the factory torque figures to build it — one book, nine sections, 404 pages. Every plate is stamped with its engine codes and platform, so you can see what changes from car to car before you order a single part. ABF runs right through the parts sections; its torque corpus isn’t published yet and is excluded, which the book tells you on the page rather than quietly leaving out.

Cut by engine, not by car
Every other reference is organised around a model. This one follows the engine across every platform it was fitted to — which is how a swap actually gets planned.
Parts, looms and torque in one book
The factory parts diagrams, the wiring looms and engine-attached electrics, and the factory torque figures — bound together, not sold as three separate references.
Every plate carries its provenance
Engine codes and platform labels are printed on the plate itself, so you can see which car and which code a given part number belongs to before you order it.
The real OEM numbers
The VW or Audi part number, position number and description for every numbered position on every diagram. What you quote at the parts counter on Monday.

Questions, answered
How is this different from the Master Parts Catalogue?
The parts catalogues are cut by car — everything fitted to a Mk2 Golf, engine to tailgate. An engine reference is cut the other way: one engine family, followed across every platform it was fitted to, with the ancillaries, looms and torque figures that belong to it. If you are restoring a car, buy the catalogue. If you are building or swapping an engine, buy this.
Are the torque figures included, or do I need the torque book as well?
They are included, in the same book, as a full section. The figure printed on the cover is the number of torque specifications inside it — for example the R32 reference carries 335. One exception is stated openly in the 16V book: the ABF appears throughout the parts sections, but its torque corpus is not yet published, so ABF torque figures are not in there.
Will this help me plan an engine swap?
That is what it was built for. Because the book follows one engine across several platforms, you can see where the part numbers agree and where they diverge between, say, a Mk4 and a Mk5 R32, or a Mk3 and a Mk4 TDI. The 4Motion driveline is carried in the R32 reference for the same reason — an R32 swap is a driveline swap.
Where does the data come from?
The factory parts catalogue data and the factory workshop manual — the same sources the dealer network used. Not forum threads, not a scan that dies when someone stops paying for a server.
What do I get, and how is it delivered?
A digital PDF at £29.95, emailed within minutes of ordering, or a printed paperback at £39.95, dispatched 3–21 days from order date. Both are A4 portrait. UK postage is £6.95, Europe £12.95, rest of world £14.95.
Every edition in this range
Restoring the whole car rather than building the engine? The Master Parts Catalogues are cut by model — every diagram for a Mk1 to Mk7.5 Golf, Passat B5, Corrado, Beetle or T2. Only after the numbers? The Master Torque References carry every factory torque figure for a model's whole engine range.
